Beetroot belongs to the botanical family of Chenopodiaceae and encompasses various variations with bulb hues that span the spectrum from yellow to crimson. It is known that the ethanolic extract from beet contains many health-beneficial and bioactive chemicals, such as alkaloids, carotenoids, phenols, tannins, and flavonoids; it also contains vitamins C, B3, B6, and B9. Hence, the beetroot extract exhibits both antioxidant and nutritional properties. The study was conducted to investigate the effects of two different drying processes, oven-drying (OD) and freeze-drying (FD), on the physicochemical qualities of betalain pigments and antioxidants. Overall, freeze-dried (FD) samples demonstrated superior retention of beetroots proximate composition when compared to those dried in the oven. This was observed in terms of minerals and antioxidants, with freeze-drying resulting in higher levels of these components compared to oven drying. On the other hand, reductions in some phenolic compounds were found in the samples treated with the freeze-drying method when compared with the oven-drying method. It was proven that red beets have a lot of phenolic compounds, including kaempferol, caffeic acid, vanillic acid, gallic acid, catechin acid, rutin, hesperidin, naringin, quercetin, and ferulic acid.</p></abstract><trans-abstract xml:lang="ru"><p>Цель данной статьи — представить обзор основных результатов исследования свеженарезанной египетской красной свеклы (Beta vulgaris). Свекла относится к ботаническому семейству Chenopodiaceae и включает в себя различные разновидности с луковичными оттенками, которые охватывают спектр от желтого до малинового. Известно, что этаноловый экстракт свеклы содержит много полезных для здоровья и биологически активных веществ, таких как алкалоиды, каротиноиды, фенолы, дубильные вещества и флавоноиды; он также содержит витамины С, В3, В6 и В9. Таким образом, экстракт свеклы обладает как антиоксидантными, так и питательными свойствами. Исследование было проведено с целью изучения влияния двух различных процессов сушки — сушки в духовом шкафу (OD) и сублимационной сушки (FD) — на физико-химические свойства пигментов беталаина и антиоксидантов. В целом, образцы свеклы, подвергнутые сублимационной сушке (FD), продемонстрировали лучшее сохранение исходного состава по сравнению с образцами, высушенными в духовке. Это было отмечено в отношении минералов и антиоксидантов, при этом сублимационная сушка привела к более высокому содержанию этих компонентов по сравнению с сушкой в духовом шкафу. С другой стороны, в образцах, обработанных методом сублимационной сушки, было обнаружено снижение содержания некоторых фенольных соединений по сравнению с методом сушки в печи. Было доказано, что в красной свекле содержится много фенольных соединений, в том числе кемпферол, кофейная кислота, ванильная кислота, галловая кислота, катехиновая кислота, рутин, гесперидин, нарингин, кверцетин и феруловая кислота.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>свекла</kwd><kwd>беталаины</kwd><kwd>феноловые соединения</kwd><kwd>антиоксидантная активность</kwd><kwd>сублимационная сушка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>beetroots</kwd><kwd>betalains</kwd><kwd>phenolic compounds</kwd><kwd>antioxidant activity</kwd><kwd>freeze-drying</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The authors are deeply indebted to Prof. Dr. Mona M.
